In the context of base training for running ultras, where there is some level of rolling terrain..
If average gradient is constant, how much might it matter if long runs / hills runs are performed up and down a mountain (all up, then all down) instead of rolling terrain?
Does the specificity matter significantly here as long as a little bit of both make their way into each week? I find it more enjoyable to hike up and run down a mountain in place of running along rolling trails for longer weekend runs.
Curious to hear thoughts on this (couldnt seem to find this topic). I expect the specificity is important, but I’m not sure how much.
Thanks!
